Numerical Solutions of 2-D Steady Incompressible Flow in a Driven Skewed Cavity

The benchmark test case for non-orthogonal grid mesh, the “driven skewed cavity flow”, first introduced by Demirdžiü et al. [5] for skew angles of 30 D D and 45 D D , is reintroduced with a more variety of skew angles. The benchmark problem has non-orthogonal, skewed grid mesh with skew angle (D ). The governing 2-D steady incompressible NavierStokes equations in general curvilinear coordinates are solved for the solution of driven skewed cavity flow with nonorthogonal grid mesh using a numerical method which is efficient and stable even at extreme skew angles. Highly accurate numerical solutions of the driven skewed cavity flow, solved using a fine grid (512 ̄512) mesh, are presented for Reynolds number of 100 and 1000 for skew angles ranging between15 165 D d d D D .
